Help with Fan placement CM690 ii

post #1 of 4
Thread Starter 
I have looked at some of the other fan options on this site and thought i would get your opinions on what i am thinking.
i currently have it set up as shown in the picture original (the floating fans are on the CPU cooler) green box = 120mm fan.
under heavy load (witcher 2 all max except uber/maybe some AA)
i get cpu temps never above 50 and gpu never above 60 but i have the GPU cooler running quite high.
i have a mildly overclocked core i5 something.
i have an unlocked 6950 and will leave at factory clock til something (probs BF3) means i will OC it.

Just wondering what people think about my proposed fan lay outs,
i prefer 'A' as keeping an OC'ed GPU cool is more important than my mildly overclocked CPU.
i will also either remove or buy aftermarket PCI slot covers cos dust is not really an issue.


Cheers.

I would go with A had a 690 II and similar fan set up worked great.

I guess you will keep the factory 140mm on top there? I would will help get some air out since hot air rises and will get air out from the top of the heatsink also.

With the fan in the 5.25 bays having a top fan intaking wouldn't make much difference. I would go with A and keep top fan in rear most spot so it wont suck the 5.25 inch fans air out b4 getting to CPU cooler.

Depends on what you'd rather cool more, the GPU area or the CPU area. That's basically what's splitting my mind between A and B for your situation. If you look through my 'stats' you'll see a very similar thread that I posted. Through the responses I got I'm thinking something like the bottom segment of your 'A' and the top segment of your 'B', but also I'm zip-tieing a fan to stack on top of the bottom HDD mounted fan. I'm assuming you're limited to fewer fans and I'm using ones that I've already purchased.

Kinda like this (Gray is no fan and no pci slots, white is blocked off):

cheers guys.

i went with same as meeps without the two floor fans or the one hanging off the hdd cage. i put another on the left panel intaking over the gpu too, seem cooler but havent stressed it yet.

and wow the panel one can vibrate loud, ended up zip-tie screwing it in and usually running it half speed!

spoo.
